In connection with the Offering, the Company issued an aggregate of (i) 70,326,229 flow-through units of the Company (‘ FT Units ‘) consisting of 64,215,117 FT Units at an issue price of C$0.50 per FT Unit and 6,111,112 FT Units at an issue price of C$0.54 per FT Unit, for aggregate gross proceeds of C$35,407,558.98 and (ii) 277,051,466 units of the Company (‘ HD Units ‘) at a price of C$0.26 per HD Unit, for aggregate gross proceeds of C$72,033,381.16.

Each FT Unit is comprised of one common share of the Company (each, a ‘ Common Share ‘) and one-half of one Common Share purchase warrant of the Company (each whole warrant, a ‘ Warrant ‘), each of which qualifies as a ‘flow-through share’ (within the meaning of subsection 66(15) of the Income Tax Act (Canada) and 359.1 of the Taxation Act (Québec)). Each HD Unit consists of one Common Share and one-half of one Warrant. Each Warrant entitles the holder thereof to acquire one Common Share (each, a ‘ Warrant Share ‘) at a price of C$0.35 per Warrant Share for a period of two years following the closing date of the Offering.

The Company intends to use the net proceeds from the HD Units towards the advancement of Company’s assets in Québec and the Northwest Territories, including the advancement of the Gaspé Copper project to a construction decision, and for general corporate purposes. The gross proceeds from the FT Units will be used by the Company to incur eligible ‘Canadian exploration expenses’ that qualify as ‘flow-through critical mineral mining expenditures’ (as both terms are defined in the Income Tax Act (Canada)) (the ‘ Qualifying Expenditures ‘) related to the Company’s projects in Québec. All Qualifying Expenditures will be renounced in favour of the subscribers with an effective date no later than December 31, 2024. In addition, with respect to subscribers who are eligible individuals under the Taxation Act (Québec), the Qualifying Expenditures will also qualify for inclusion in the ‘exploration base relating to certain Québec exploration expenses’ within the meaning of section 726.4.10 of the Taxation Act (Québec) and for inclusion in the ‘exploration base relating to certain Québec surface mining exploration expenses’ within the meaning of section 726.4.17.2 of the Taxation Act (Québec).

The Offering was led by Canaccord Genuity Corp. as sole bookrunner together with BMO Nesbitt Burns Inc. and National Bank Financial, as lead underwriters, for and on behalf of a syndicate of underwriters that included Scotia Capital Inc., CIBC World Markets Inc., RBC Dominion Securities Inc. and TD Securities Inc. (collectively, the ‘ Underwriters ‘). In consideration for their services, the Underwriters were paid a cash commission equal to 5% of the gross proceeds of the Offering.

All securities issued under the Offering are subject to a hold period expiring four months and one day from the date hereof. The Offering remains subject to final acceptance of the TSX Venture Exchange.

Certain directors and officers of the Company subscribed for an aggregate 3,464,931 HD Units for aggregate gross proceeds of $900,882.06. Each director and officer of the Company is considered an ‘insider’ of the Company and, as a result, their participation under the Offering is considered to be a ‘related party transaction’ for the purposes of Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (‘ MI 61-101 ‘). The Company is relying on exemptions from the formal valuation and minority shareholder approval requirements available under MI 61-101. The Company is exempt from the formal valuation requirement in section 5.4 of MI 61-101 in reliance on section 5.5(a) of MI 61-101 as the fair market value of the transaction, insofar as it involves insiders, is not more than 25% of the Company’s market capitalization. Additionally, the Company is exempt from minority shareholder approval requirement in section 5.6 of MI 61-101 in reliance on section 5.7(1)(a) of MI 61-101 as the fair market value of the transaction, insofar as it involves insiders, is not more than 25% of the Company’s market capitalization. The Company did not file the material change report more than 21 days before the expected closing date of the Offering as the details of the Offering and the participation of insiders therein was not settled until shortly prior to the closing of the Offering, and the Company wished to close the Offering on an expedited basis for sound business reasons.

Certain incoming directors and officers of the Company have also subscribed for an aggregate of 11,208,144 HD Units under the Offering for an aggregate gross proceeds of $2,914,177.
